"Why should I be alarmed by these trifles when I am contemplating such a desperate deed?" thought he, and he gave a strange smile. "Ah, well, man holds the remedy in his own hands, and lets everything go its own way, simply through cowardice--that is an axiom. I should like to know what people fear most: whatever is contrary to their usual habits, I imagine. But I am talking too much. I talk and so I do nothing, though I might just as well say, I do nothing and so I talk. I have acquired this habit of chattering during the last month, while I have been lying for days together in a corner, feeding my mind on trifles. Come, why am I taking this walk now? Am I capable of that? Can that really be serious? Not in the least. These are mere chimeras, idle fancies that flit across my brain!"
